Re: no sound + backlit keyboard not lighting up (PowerBook G4/Sarge)

'ello,

[ I seem to have missed some of this thread, including a bounce of my
original post (which I'm set up to receive) so I am not too clear on
some of the suggestions you're referring to.  Apologies to anyone I
appear to be ignoring -- I don't seem to have got the mails ]

Thanks for the suggestions.

I've got alsa-base and alsa-utils and have set the mixers to a high
volume (I've been caught out by the fact they're on 0 to start with in
the past :-)).

I don't think I received the mail from Elimar, so I am not exactly sure
what was suggested, but I have checked that I'm in the audio group and
the permissions seem sane to me.  (you can find them below)

I'm wondering if I am meant to follow the steps relating to ALSA on the
following page:

http://www.mathematik.uni-marburg.de/~schmidtm/apple/powerbook.en.php

I opted not to, for now, because I thought it might cause complications
(the article is not describing the same computer as mine).

I may try this in the future.

Hmmm, it's not currently on my system, it seems.  I will probably have
to recompile the kernel.  When I do this I will try and fix the sound
issues and the video mode it starts in (currently the text is to small
to read [that's another e-mail that I don't think made it to the
list...]).

Is there a standard PowerBook G4 15'' 1.5GHz (PowerBook5,4) kernel
.config lying around anywhere by any chance? :-)

bye just now, best regards,


Matthew
